H1 Extn denied, i94 expired - old petition still valid


My H1 extn denied and I94 expired in FEB 2020.
But i have an old petition ( same employer) valid till oct 2020 but different location.

Can i move to old location with Oct 2020 petition ? I am hearing that old petition i94 is not valid anymore after i filed amendment and it got approved with new i94 until Feb2020.

You can move to old location if the H1B petition is still valid and has not been withdrawn.

You will need to file an H1B Extension immediately there.

Thanks for your reply.
As its the same employer the old petition showing valid in USCIS case status.
